High-end Refractory Material - Alumina Fiber

Alumina fiber is a high-performance inorganic fiber, although the name is not reflected, its composition is not limited to Al2O3, some also contain SiO2 and B2O3 and other metal oxide components and is a very high-end refractory material.

As one of the world's new ultra-lightweight high-temperature refractory fibers, alumina fiber can not only maintain good tensile strength at higher temperatures and long-term use temperatures of 1450-1600℃; Moreover, the surface activity is good, and it is easy to compound with resin, metal and ceramic matrix to form many properties and widely used composite materials. At the same time, it also has the advantages of small thermal conductivity and low thermal expansion coefficient and is also very good at "fire insulation", which has been widely used in aerospace, nuclear power, and automotive industry.
